在python 2.7.9中禁用默认证书验证

Posted 2021-03-31

我尝试与XMLRPC api建立本地HTTPS连接。自从我升级到enable by default certificates verification的python 2.7.9后，我在使用API​​时遇到了CERTIFICATE_VERIFY_FAILED错误

>>> test=xmlrpclib.ServerProxy('https://admin:bz15h9v9n@localhost:9999/API',verbose=False, use_datetime=True)
>>> test.list_satellites()

在python 2.7.9中是否存在禁用默认证书验证的pythonic方法？

我真的不知道改变“私有”全局SSL属性是否有用（ssl._create_default_https_context = ssl._create_unverified_context）

答案

您必须提供未经验证的SSL上下文，手动构建或使用ssl模块中的私有函数_create_unverified_context（）：

import xmlrpclib
import ssl

test = xmlrpclib.ServerProxy('https://admin:bz15h9v9n@localhost:9999/API',
                             verbose=False, use_datetime=True, 
                             context=ssl._create_unverified_context())
test.list_satellites()

注意：此代码仅适用于python> = 2.7.9（在Python 2.7.9中添加了contextparameter）

如果您希望代码与以前的Python版本兼容，则必须使用transport参数：

import xmlrpclib
import ssl

context = hasattr(ssl, '_create_unverified_context') and ssl._create_unverified_context() 
          or None
test = xmlrpclib.ServerProxy('https://admin:bz15h9v9n@localhost:9999/API',
                             verbose=False, use_datetime=True, 
                             transport=xmlrpclib.SafeTransport(use_datetime=True, 
                                                               context=context))
test.list_satellites()

另一答案

可以使用Python 2.7.9+上现有的公共ssl API禁用验证：

import xmlrpclib
import ssl

ssl_ctx = ssl.create_default_context()
ssl_ctx.check_hostname = False
ssl_ctx.verify_mode = ssl.CERT_NONE
test = xmlrpclib.ServerProxy('https://admin:bz15h9v9n@localhost:9999/API',
                             verbose=False, use_datetime=True, 
                             context=ssl_ctx)
test.list_satellites()

另一答案

以Python 2.6.6为例：

s = xmlrpclib.ServerProxy('https://admin:bz15h9v9n@localhost:9999/API', transport=None, encoding=None, verbose=0,allow_none=0, use_datetime=0)

这个对我有用...
